Issue
Some properties or methods return an object. But I did not know how to check its type. e.g. I would like to determine the Proxy ObjectType returned from Constraint.EntityOne (i.e. If oConst.EntityOne = kWorkPointProxyObject
Solution
Two ways you could use. Please refer to the code below. One uses TypeOf. Another get the Object.ObjectType which is a value of the enu ObjectTypeEnumm.
Sub tesObjectTypeEnumt() Dim oAsmDoc As AssemblyDocument Set oAsmDoc = ThisApplication.ActiveDocument Dim oAsmCompDef As AssemblyComponentDefinition Set oAsmCompDef = oAsmDoc.ComponentDefinition Dim oConstraints As AssemblyConstraints Set oConstraints = oAsmCompDef.Constraints Dim oCons As AssemblyConstraint Set oCons = oConstraints(1) Dim oEntityOne As Object Set oEntityOne = oCons.EntityOne 'way1 If TypeOf oEntityOne Is EdgeProxy Then End If 'way2 Dim objType As ObjectTypeEnum objType = oEntityOne.Type If objType = kEdgeProxyObject Then End If End Sub
